[pve-devel] [PATCH manager v7 2/2] fix #4849: ui: download to storage: automatically dectect and configure compression

[Philipp Hufnagl]

extends the download iso prompt with a "compression algorithm" drop down
under advanced. User can configure there if a decompression algorithm
should be used from the storage backend. The compression algorithm will
be automatically guessed when calling query_url_metadata
